Wow! How great to come here and get all of this awesome feedback! Thanks guys!

Ok, so maybe all of you experienced cruisers can tell me if you think any of these itineraries are really more exotic/exciting than the others? I like the idea of sailing out of New Orleans, b/c we just love New Orleans. And Jamaica sounds like fun (although I'm torn about some human rights issues there, but anyway). The Western Caribbean trip on the Dawn is the one that sounds the most exotic to me - Central America with monkeys and rain forests ... or am I terribly wrong? Are these places all virtually the same with minor differences in cultures? I swear I'm making this into the biggest decision of my life.
